Abstract

Abstract: This paper proposes a novel data hiding method for binary images authentication based on analyzing the measurement of document images and considering the structure of Chinese character.First unify the pixels flippability scores and the Chinese character structural feature，choose 16 standard modules，and then choose 8 best flip patterns module according to DRDM rule，flip the 8 best flip patterns module to embed watermark.The experiment shows this algorithm has best visual quality，and can be used to location the tampers at the same time.

Key words: Chinese character structure, binary document, authentication, visual quality

摘要： 在深入分析二值文本隐藏技术评价准则的基础上，结合汉字笔画结构特点，提出了一种具有最佳视觉效果的认证数字水印方案。首先结合像素可翻动性评分准则与汉字结构特征，选择标准的16模块，然后在此模块中依据DRDM准则选择最佳翻动8模块，翻动图像中的8模块来嵌入水印信息，实验表明该算法视觉隐蔽性极佳，并能完成篡改定位。
